The Johnson & Johnson one-shot coronavirus vaccine could be proven to work by next week, though FDA regulators still need to approve the new vaccine.

Not only is this vaccine cheaper, but it also doesn’t need to be stored at sub-zero temperatures. And with only 6.2% of the US vaccinated, their vaccine could speed the process since it requires just one dose.

The FDA has signaled it might not give Emergency Authorization until March, which has many people asking why it would take them so long.
